目的为了简化手术步骤,方便操作,提高手术成功率。方法采用wistar大鼠(200～250g)为供体,SD大鼠(200～250g)为受体,行同种带瓣主动脉腹主动脉补片式异位移植36例。供体经修剪保留两个主动脉瓣叶及相应宽度瓣下附着心肌(0.5mm)和主动脉壁(5mm),三定点连续缝合法移植于左肾静脉下方腹主动脉前壁。结果手术成功率为94.4%。结论实验结果提示:与腹主动脉间置式移植相比,本手法操作简单,成功率高,可满足类似实验要求。 Objective To simplify the surgical procedures, facilitate operation and improve the success rate of surgery. Methods Wistar rats (200 ~ 250g) were used as donors and SD rats (200 ~ 250g) as recipients. Allograft flap aorta patch-like allotransplantation was done in 36 cases. The donor was trimmed to retain both aortic valve leaflets and the corresponding width of the flap attached to the myocardium (0.5mm) and the aortic wall (5mm), three-point continuous suture graft in the anterior wall of the left renal artery below. Results The successful rate of operation was 94.4%. Conclusion The experimental results suggest that compared with the indirect abdominal aorta transplantation, the method is simple, high success rate, to meet the requirements of similar experiments.
